- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation located for USS John Penn (APA-23/AP-51) in any authoritative source searched. As a 1931-built liner sunk in 1943, no post-war survey or abatement record exists. This is a negative finding, not an absence of exposure.
